Application filed June 3,

This invention relates to certain new and useful improvements in snap hooks and pertains more especially to a hook which is particularly adapted for use with watch cases having ornamental ends.

A great many watch cases of present day manufacture have ornamentaleuds so attached as to render it ditlicult to secure the bracelet ends to the watch loops with the present form of hook, the present invention aiming to provide an improved form of hook which enables the same to be easily and quickly engaged with and disengaged from the watch loops.

A further object of the invention is to provide a hook which can be engaged without manual manipulation of the hook to open same prior to being engaged with the loop.

Still further, the invention aims to provide a hook structure which is of simple, compact and economical form, and which is positive in its operation.

In the drawings Fig. 1 is a top plan view of the present invention applied to a watch;

Fig. 2 is a side edge elevation;

Figure 8 is a detail bottom plan view, partly broken away and in section of the invention, and

Figure 4 is a section on line ei l of Fig. 3.

In proceeding in accordance with the present invention the hooks are each composed of a hollow casing 1 having inturned side flanges 2 at the shank of the casing which flanges are employed to secure the back plate 3 in position. lhe forward ends of the tops of the casings are formed with out-turned guide fingers or lips 4E located at the centers of such ends. The hooks proper have bodies 5 formed with a spaced pair of hook members 6 which latter receive the lips 4 in the space therebetween, the hook members 6 facing upwardly so as to co-operate with the top of easing 1 to hold the usual end loops L of the watch lV therebetween. The hook body 5 is formed with a curved or semi-circular operating member '7 which projects through a slot 8 provided therefor in the top of the casing 1 and has a finger engaging projection 9 on its top. The body 5 is further formed with pivoting pintles 10 that are received in journals 11 provided therefor at the forward end of the back plate 8. The member 7 is formed with a lateral arm 12 about which a coil spring 18 is engaged,

the spring having an end 1 lwhich rests on the body. The spring 13 further has a coil portion 15 which seats on plate 5 and is housed by the member 7, and has an end 18 which rests on the back plate 3.

In operation, in attaching a hook, the iembers l and 6, which, as shown in Figure 4, form a guide in a somewhat V shaped arrangement, are engaged'with the loop L and moved inwardly toward the watch, whereupon the hook 6 cams against the loop, thereby opening the hook and holding the parts as shown to the left of Fig. 2. In order to release the parts, the projection 9 is engaged by one of the fingers of the user and the hook 5 depressed, as shown to the right of Figure 2, whereupon the parts are moved away from the loop.

Having thus described my invention what I claim as new and desire to secure byLetters Patent is 1. In a hook, a casing having an upwardly and outwardly extending finger at its front, a spring tensioned hook composed of a plate pivoted to the casing and having a pair of hook members at its front receiving the finger therebetween, the hook members being formed to cam against a watch loop simultaneously with engagement of the loop by the finger, and means to depress the hook from the casing top.

2. In a hook, a casing having a slotted top and an upwardly and outwardly extending finger at its front, a spring tensioned hook composed of a plate pivoted to the casing and having a pair of hook members at its front receiving the finger therebetween, the hook members being formed to cam against a watch loop simultaneously with engagement of the loop by the finger, and an operating member for the hook carried by the hook plate and extending upwardly through the slot of the casing. V

3. In a hook, a casing iaving an outwardly and upwardly extending finger at its front, a. spring tensioned hook member pivoted to the casing, and a pair of upwardly facing hook members carried by the hook member and cooperating with the finger to enable the hook to be applied to a watch loop by movement of the hook toward the loop and with the latter having camming engagement with the finger and with the hook members.

4:. In a hook, a casing having an outwardly and upwardly extending part at its front,

a spring tensioned hook member pivoted to the casing and an upwardly facing hook proper carried by the member and co-operating with the finger to enable the hook to be applied to a watch loop by movement of the hook toward the loop and with the latter having camming engagement with the finger and with the hook member.

5. In a hook, a casing having an outwardly and upwardly extending part at its front, a spring tensioned hook member pivoted to the casing and an upwardly facing hook proper carried by the member and co-operating with the finger to enable the hook to be applied to a watch loop by movement of the hook toward the loop and with the latter having camming engagement with the finger and with the hook member and means for operating the hook member from the top of the casing.

6. A hook composed of a casing having a watch loop engaging part at its top, a tensioned hook member carried by the casing and having a hook facing upwardly whereby to cooperate with the said casing part to enable the latter and the hook to have camming engagement with the loop so as to automatically connect the hook to the loop.

7 In combination with a casing having a loop engaging part, a tensioned hook member carried by the casing and having a hook faced toward the casin the said )art and the hook having relatively divergent adjacent parts so as to enable the loop to have camming engagement with each of the said divergent parts so as to move the hook to open position.

In testimony whereof l have signed my name to this specification.
